Summoner Champion?

So in League there are a good few champions that have minions of sorts, such as Malzahar's voidling, Yorick's ghouls, Zyra's plants, etc... but I was wondering if riot has any plans to create a champion that is fully focused on summoning abilities? A summoner champion could be really neat and unique, with each of his 4 skills being a different kind of creature he summons that does different stuff - and then maybe a passive that enhances him/her or the summons based on how many are out. I would love to see a champion like that added to league. What about you guys? Any thoughts?
